Parking too small

[Faize31]

Hi,
In some airports, GSX tells me that the aircraft parking lots are too small for my aircraft.
Can you tell me what are the criteria of GSX to determine if a place is too small or not?

 GSX uses the parking spot sizes from the scenery. These parking spots were made to just add parking, and commonly aren't very accurate for size at all.
 Luckily, you can adjust them easily within the sim using GSX and only takes about 10 seconds. See page 38 of the GSX manual, Max Allowed Wingspan.
